Remarks

The typical y-axis skew means skews the angle in degrees counterclockwise from the x-axis. However, because the y-axis in Direct2D is inverted, the y-axis skew angle in Direct2D means skew the angle in degrees clockwise from the x-axis.

For example, the following illustration shows the rectangle skewed with y-axis skew angle of 30 degrees. Notice that the angle is 30 degrees clockwise from the x-axis.
